Looks to me like they were just a bit out of practice, they missed the coins center =) I had an 1883 IH that was precisely in the center, used to keep it laying on my dresser for display item and conversation piece. The only problem was my mom kept putting it in my change collection. One day I took my change collection to the bank back in the 1990s and the teller took my coins back to get them counted/sorted and after a bit I heard a loud bang explosion sorta sound. Evidently it destroyed their machine. Hope the new changers are made better!
